Django 1.5 - 登录

Question

创建UserProfile模型后。我开始创建登录，但由于get_user（）错误而卡住了。

EXCEPTION

AttributeError: 'LoginForm' object has no attribute 'get_user' 

这里是我的代码：

UPDATE

class LoginView(FormView): 
    form_class = LoginForm 
    redirect_field_name = REDIRECT_FIELD_NAME 
    template_name = 'login.html' 
    success_url = '/' 

    def form_valid(self, form): 
     username = form.cleaned_data['username'] 
     password = form.cleaned_data['password'] 

     user = authenticate(username=username, password=password) 
     if user is not None: 
      if user.is_active: 
       login(self.request, user) 
       return HttpResponseRedirect(self.get_success_url()) 
     else:   
      return self.form_invalid() 

    def form_invalid(self): 
     return HttpResponseRedirect(reverse('accounts:login')) 

    def get_success_url(self): 
     if self.success_url: 
      redirect_to = self.success_url 
     else: 
      redirect_to = self.request.REQUEST.get(self.redirect_field_name, '') 

     netloc = urlparse.urlparse(redirect_to)[1] 
     if not redirect_to: 
      redirect_to = settings.LOGIN_REDIRECT_URL 
     elif netloc and netloc != self.request.get_host(): 
      redirect_to = settings.LOGIN_REDIRECT_URL 
     return redirect_to 

    def post(self, request, *args, **kwargs): 
     form_class = self.get_form_class() 
     form = self.get_form(form_class) 
     if form.is_valid(): 
      return self.form_valid(form) 
     else:     
      return self.form_invalid() 

如何解决这一问题？任何帮助，将不胜感激。我在Django 1.5上真的很新。需要帮忙。

在原始代码中，作者是做称为get_user形式方法内的authenticate东西。你已经在表单之外完成了，所以只需将form.get_user()替换为user即可。

我用的是不是基于类的登录视图，而我甚至不关心到使用Django的表单实例，但它应该很容易适应：

def signin(request): 
    if request.method == 'POST': 
     user = authenticate(
      email=request.POST.get('username', '').lower().strip(), 
      password= request.POST.get('password', ''), 
     ) 
     if user is None: 
      messages.error(request, u'Invalid credentials') 
     else: 
      if user.is_active: 
       login(request, user) 
       return HttpResponseRedirect(request.GET.get('next', '/')) 
      else: 
       messages.error(request, u'User is not active.') 

    return render_to_response('login.html', locals(),  
         context_instance=RequestContext(request))

为表单定义get_user方法。

未经测试（但应该让你在正确的道路）：

def get_user(self): 
    from django.contrib.auth import authenticate 
    return authenticate(
      email=self.cleaned_data.get('username', '').lower().strip(), 
      password=self.cleaned_data.get('password', ''), 
    )
